Existe uma maneira de limitar o maxdepth para ls -Rhal?

Question

Existe uma maneira de limitar o maxdepth em um comando ls -Rhal ? Estou ciente do find . -maxdepth , mas quero poder obter as informações do arquivo que vem com ls -Rhal .

    

Answer 1

Isso pode ajudar:

1. Use find do -printf , isso dará o tamanho dos arquivos em Kb, então não é bem assim ls -lh :

   find . -maxdepth 2 -printf '%M %n %u %g %kK %Tc %p\n'

   Explicação:

   -printf format

         %M     File's permissions (in  symbolic  form,
                as  for  ls).   This  directive is sup‐
                ported in findutils 4.2.5 and later.
         %n     Number of hard links to file.
         %u     File's user name, or numeric user ID if
                the user has no name.
         %g     File's  group name, or numeric group ID
                if the group has no name.
         %k     The  amount of disk space used for this
                file in 1K blocks. Since disk space  is
                allocated  in multiples of the filesys‐
                tem block size this is usually  greater
                than   %s/1024,  but  it  can  also  be
                smaller if the file is a sparse file.
         %Tk    File's last modification  time  in  the
                format  specified  by  k,  which is the
                same as for %A.
   
                c      locale's  date and time (Sat Nov
                       04 12:02:33 EST 1989).  The for‐
                       mat  is the same as for ctime(3)
                       and so to preserve compatibility
                       with  that  format,  there is no
                       fractional part in  the  seconds
                       field.
         %p     File's name.
   

2. Use find da opção -ls :

   find . -maxdepth 2 -ls

   Explicação:

   -ls    True;  list current file in ls -dils format on
         standard output.  The block counts are  of  1K
         blocks,   unless   the   environment  variable
         POSIXLY_CORRECT is set, in which case 512-byte
         blocks  are  used.   See the UNUSUAL FILENAMES
         section  for  information  about  how  unusual
         characters in filenames are handled.
   

3. Use a sugestão de @mpy (esta é provavelmente a melhor solução):

   find . -maxdepth 2 -type d -print0 | xargs -0 ls -hal

   Explicação:

   -exec command ; 
         Execute command; true if 0 status is returned.
         All following arguments to find are taken to be
         arguments to the command until an argument consisting of
         ';' is encountered.  The string '{}' is replaced by the
         current file name being processed everywhere it occurs
         in the arguments to the command, not just in arguments
         where it is alone, as in some versions of find.  Both of
         these constructions might need to be escaped (with a
         '\') or quoted to protect them from expansion by the
         shell.  See the EXAMPLES section for examples of the use
         of the -exec option.  The specified command is run once
         for each matched file.  The command is executed in the
         starting directory.  There are unavoidable security
         problems surrounding use of the -exec action; you should
         use the -execdir option instead.
